URINALYSIS – BCSE Study Guide

Overview and Clinical Importance

Urinalysis is one of the most fundamental and cost-effective diagnostic tests in veterinary medicine, providing critical information about the urinary system and systemic health. A complete urinalysis includes three components: physical examination (color, clarity, specific gravity), chemical analysis (dipstick testing), and microscopic sediment examination.

On the BCSE, expect questions integrating urinalysis interpretation with clinical scenarios, particularly distinguishing prerenal versus renal azotemia, identifying crystalluria and its clinical significance, and understanding the protein:creatinine ratio (UPC) for proteinuria assessment.

Section 1: Urine Specific Gravity Interpretation

Urine specific gravity (USG) measures the kidney's ability to concentrate or dilute urine relative to plasma. It reflects the total mass of solutes dissolved in urine and is the MOST IMPORTANT parameter for assessing renal concentrating ability.
